Single Zener Diodes Procurement Notes

Verify the specific suffix 'B' confirms the required ±5% voltage tolerance, as standard versions may differ. Confirm the '-TP' designation aligns with the intended tape and reel packaging format. Ensure compliance with RoHS directives and check for any lead-in-glass exemptions relevant to your assembly process. Validate that the component meets all environmental requirements for your specific operating conditions.

Single Zener Diodes Selection Notes

Select this component when a precise 82 V reference is needed with tight tolerance limits. The DO-35 package suits designs requiring robust mechanical leads and high thermal stability. Consider the positive temperature coefficient for circuit compensation strategies. Evaluate the 500 mW power rating against expected load currents to ensure safe operation within derating curves.

Single Zener Diodes Part Context

This part belongs to the 1N5268 through 1N5276 series, covering voltages from 82 V to 150 V. All devices share identical physical dimensions and maximum ratings, differing primarily in breakdown voltage and associated impedance values. The series utilizes a standardized glass axial construction suitable for general-purpose industrial electronics.

Single Zener Diodes Replacement Considerations

Cross-reference other manufacturers offering 1N5268 equivalents in the DO-35 package. Verify that substitute parts match the 82 V nominal voltage, 500 mW power rating, and ±5% tolerance. Ensure the replacement maintains similar leakage and impedance characteristics for circuit compatibility.
